In the proto-historical time, on today S-shaped land of Vietnam, there were three brilliant archaeological cultures: Dong Son, Sa Huynh, Oc Eo. They were three cultural transmitting centers in Southeast Asia and beyond. Among these centers, in my point of view, Dong Son culture is more pervasive both in space and time. In terms of space, there have been many monographs mentioning the effects of Dong Son culture on contemporary cultures. In terms of time, however, there is almost no research that explains the nature of the preservation of Dong Son elements in the national cultural flow. In this article, I am going to show the effects of Dong Son art in the post-Dong Son periods in Vietnam. At the same time, I also analyze the geo-political and geo-cultural context that made Dong Son a long-lasting vitality in the Vietnamese cultural tradition.
